Specification of Letters Patent. Patented June 14, 1921.

Application filed March 5, 1919. Serial No. 280,779.

To all whom t may concern.'

Be it known that I, REGINA N. BnEssLEn, a citizen of the United States, residing at New York city, in the county of New York and State of New York, havey invented certain new and useful Improvements in InflatingValves, fully described and represented in the following specifica-tion and the accompanying drawings, forming a part of the same.

This application is in part a division of my application, Serial No. 64,4%, filed December l, 1915, for swimming devices, with the vaddition of improvements upon the structure disclosed in said application in respect to the valve cap and means forattaching it to the bag, or swimming device.

f The invention relates to inflating devices, or valves, especially suitable for inflatable floats of swimming devices, but which may also be used in other inflatable containers.

Among the objects of the invention are, to provide a simple and easily operated valve adapted for the purpose indicated and for analogous uses, means associated with the valve for securing it in operative position in a novel and effective way, means for retaining air pressure temporarily, in a convenient way, while the valve is being closed, and means for connecting the valve cap to the float or bag with which thev inflating device is used.

Other objects and advantages of the invention are sufliciently explained hereafter.

To attain the foregoing and otherobjects, and to incorporate structural and operative advantages sufficiently pointed out hereafter, the invention comprises a combination of parts of which the accompanying drawing shows one representative embodiment. After considering this embodiment, it will be understood that the structure may be varied within the principles of the invention, and I do not limit myself to details except as claimed.

Figure l is a longitudinal section of the vform of valve cap with its attaching cordj Fig. 5 is a longitudinal section of the same.

Fig. 6 is a side view of one form of in-` flatable bag with my valve in place, showing also a cord connecting the valve cap with the bag.

The floats of swimming devices with which my valve is especially designed to be used, are usually in the form of bags made of textile fabric which is preferably not treated to make it air-tight, but which when wet contains air as securely as is desired for the purpose, as understood by persons familiar with that art, and as explained in my application above mentioned. Such bags are usually formed with a neck la of moderate diameter to receive the valve, and the valve and its associated` parts are especially devised to be secured in a satisfactory way to such a neck when formed of textile fabric of the character above described, although the valve is also well adapted to be secured to suitably formed necks of bags or air containers composed of other material, such as rubber or rubberized or otherwise treated fabric. 4

The valve comprises a tubular body or nipple lo having an air passage 16 through which air may be supplied to the interior of the swimming device float F, or inflatable member; and 1'1" designates acollapsible and resilient tube or sleeve of india rubber or other suitable flexible and elastic material, the outer end of which surrounds the lower or inner end of the nipple, said tube extending beyond the end of the nipple andinto the interior of the inflatable member, `as shown.

In providing the valve device and securing itin place as above explained, the nipple and collapsible tube are assembled and placed within the neck 14, and a ferrule 18 is placed over the neck as shown in Figs. ly and 3. This ferrule is made from a suitable metal or other material which may be readily compressed to reduce the diameter thereof, and after the parts have been assembled as above, the ferrule is compressedby a suitable mechanism or device whereby its diameter is reduced to such an extent that the neck lll is forced against the outside of the tube 17,' and the upper end of said tube forced against the inner roughened end of the nipple l5; thus securing a binding engagement betweenthe 'several parts and l holding the nipple, tube and ferrule in place,

as will be understood; the various elements assuming the condition shown in Fig. 2 after the nipple has been fully compressed.

The tube 17 notlonly Serves as a packing between the ferrule and neck 14- andthe nipple l5, but the inner projecting end of thistube serves to protect the adjacent portions of the float member by preventing their drawing directly against the end of the nipple, and also serves as a means whereby the escape of air through the nipple may be temporarily prevented.

VThe outer end of the nipple is closed by a removable lcap 19 in threaded engagement therewith and provided with a packing 20 so that when the cap is screwedinto place the escape of air from the iniata'ble member will be prevented. In order to prevent the p cap 19 from being lost, it may be connected to the swimming device l" by means ot' `a llexibletape or other cord 2l which will not interfere with the screwing of the cap on to or olif from the end of the nipple, but will effectually prevent lits loss when detached `from the nipple. Y

To inflate a float to `which the valve is attached as above described, its valve cap 19 is removed and air is supplied to the float through the nipple by blowing in from the mouth or otherwise. After the float member has been sufficiently inflated, or between breaths, the escape of air is temporarily prevented by Vcollapsing or flattening `the inwardly extending end of the tubevl?, this being readily accomplished by pressing the adjacentportions of the wallof t-he inflat able member inward as by pressure-of the thumb andrfinger, such pressu'rebeing transmitted through the walls and to the end of the tube tocollapse the same. Theescapo of air from the inatable member `may thus be readily prevented until the closing cap is screwed on to the end kof t-he nipple,

Y after .which the tube maybe Vreleased and escape of air will be prevented by the cap.

An improved formof valve cap 19a, which is preferred in some cases, is shown in Figs. et, 5 and 6. This cap is usually of stamped or pressed sheet metal and contains the usual packing 20a and is y interiorly threaded at 22 to engage the valvestem. The

cap also hasa tubular extension 28, the

end of which is pressed in to forman annular shoulderQ, and having an end opening of reduced diameter Y as compared to theV bore of the tubular extension. The valve cap stem also has at leastfone hole 25 in its rwall located somewhat below the "shoulder 24, and usuallythcre are two of these holes oppositelylooated,=-asfshown, sothat they can be conveniently formed in the'valve cap stem by drilling straight through it. lith thisfform of valve cap, the attaching cord 2l may be secured to the cap by passing one of its ends through the hole in the upper end of the valve cap past the shoulder 24k and out through either of the holes 25. A knot 2G is then tied in the end of thecord andthe cord pulled back, so that theknot passes through the hole 25 and engages underneath the shoulder 24 and thus forms an attachment of the cap to the cord. The other end of the cord is connected to the float F of the swimming device at 27. The described construction not only provides a very cheap and satisfactory means for connecting the removable valve cap with the bag, but it provides in effect 4a swivel conncction'between the cord and the cap, so that undue twisting of the cord is avoided when the .valvecap is rotated in attaching andv detaching it. Y

What is lclaimed is:

l. A valve for inflatable bags, comprising a tubular body, a sleeve of compressible ma.- terial surrounding a part `of the length of the body'V and adapted to fit withiir the neck of the air bag, clamping meansadapted to extend about theneck of the bagupon said sleeve to force the neck against the sleeve and the vsleeve againstthe body and secure the body, sleeve andneck together, and means for opening and closing thevalve. Y
